jQuery validate插件-货币 [英] jQuery validate plugin - currency

问题描述

我正在尝试找出如何验证jQuery validate插件中的数字为合法的美国货币，最多两个小数位零，而没有逗号或美元符号(25000.00、1.00等)

I am attempting to figure out how to validate a number in the jQuery validate plugin as legitimate US currency, max two decimal place zeroes, without commas or dollar signs (25000.00, 1.00 , etc)

我尝试了这个要点 https://gist.github.com/jonkemp/9094324 ，但似乎需要美元符号($)

I attempted this gist https://gist.github.com/jonkemp/9094324, but it seems to require the Dollar sign ($)

        jQuery.validator.addMethod("currency", function (value, element) {
      return this.optional(element)
        || /^\$(\d{1,3}(\,\d{3})*|(\d+))(\.\d{2})?$/.test(value);
    }, "Please specify a valid amount");

我还尝试了此堆栈溢出使用jQuery验证货币的客户端验证字段 但验证码不会验证带有两个零(例如1.00)的数字

I also attempted this Stack Overflow cliente validation using jQuery validate for currency fields but the validation code will not validate a number with two zeroes (1.00 for instance)

jQuery.validator.addMethod("currency", function(value, element) {
    var isValidMoney = /^-?(?:\d+|\d{1,3}(?:\.\d{3})+)(?:,\d+)?$/.test(value);
            return this.optional(element) || isValidMoney;
        },
        "Must be monetary (0 or 0.00)"
    );

只需包含 additional-methods.js文件，然后按如下所示使用内置的currency方法...

Simply include the additional-methods.js file and use the built-in currency method as follows...

currency: ["$", false] // dollar sign optional

currency: "$" // dollar sign required (default)

注意:在所有情况下，逗号都是可选的.

Note: commas are optional in all cases.

注意:您的jsFiddle 还包含

NOTE: Your jsFiddle also contains a DOM ready handler inside of another DOM ready handler. While it's not harmful, it's totally superfluous.

$(function() {  // <- DOM Ready Handler

    $(document).ready(function() {  // <- DOM Ready Handler
        ....
